wierd vodafone 750 behaviour outside the UK

Hi all, i recently got a vodafone Treo Palm 750 from a friend who bought it from the UK.
I'm currently outside the UK...now when i try to put my non-UK sim card into the phone, it logs on normally to my GSM network however the phone exhibits the following weird behaviour.
1) SMS send and receive works normally.
2) I cannot make a call... phone starts dialing then hangs up by itself immediately.
3) When someone calls me i can receive the call... but my microphone and speaker are off so that i cannot hear the person nor can they hear me... in other words i cannot make or receive voice calls.
4) Despite having the tap sound turned on, the touch screen makes no sound when tapped.
5) Even after pairing with another phone, i am unable to send files to the treo over bluetooth.
Basically the situation is I cannot use the phone for calls yet i can send SMS. Now I don't know anything about the different types of phone locks and have never worked with locked phones, but is this behaviour caused by some wierd thing vodafone did to prevent me using the phone outside the UK ? If so why would they let me use my non-UK simcard to SMS but not call ?
The phone has no scratches so i doubt this is a hardware issue caused by the phone falling previously.
Please give me any idea about why this is happening and how i can fix all issue so i can use this phone throughout the world. (btw i did a soft reset but no difference... i don't want to do a hardware reset because if this phone is somehow partially unlocked then it may revert back and i won't even be able to use my non-UK sim outside the UK to SMS).
Thanks

[Completed] [Q] S4 dialer problem

Hello all, I have a samsung galaxy s4 model # i377m that was locked to bell. I purchased a unlock code for the phone and used a Kooko-(telus) sim card to enter the code. The code was successful however when I put my bell sim card back in the phone I can't send or receive phone calls properly. The dialer app opens and I can see my call history and browse my contacts but when I go to place a call the phone goes buggy, it will place the call but my screen goes black and I can't hear or be heard on the receiving end. It's really weird because everything else on the phone works, I have full reception and have the ability to send and receive txt and use data. The phone has a custom rom Cyanogenmod 12. I thought the rom had something to do with it so I downloaded and installed the stock firmware and I still had the same problem. At this point I have put cm12 back on the phone and must wait until someone can help me. I'm really lost for words.
Thanks for taking the time out of you're day to help me

Hi
Thanks for writing to us at XDA Assist. Have you tried inserting a different SIM into the device?

Sim unlock S5 Sport Sprint G860P strange problem :(

Hi guys, i have two G860p and tried to unlock them for using in New Zealand
Both of them running android 5.0 and i used the idoneapps to unlock it
For the FIRST one, the phone got signal, can send text, use 3G data, make phone call BUT ONLY UNABLE TO RECEIVE phone call. There is always an error of "Unfortunately the process com.android.phone has stopped" when other people call me. I did factory reset and used the another unlock method - bring back to 4.4.4 and unlock by SU.apk (http://forum.xda-developers.com/spr...sim-unlocking-sprint-galaxy-s5-g900p-t3085624) but it still has the same issue. After that i dialed ##72786## to bring the phone back to original setting to find another solution. One day after that, i realize that i didn't enable the GCF after unlock the phone and tried to do it immediately with the hope that it will solve my issue. Unfortunately, the issue still happen and i also have a new trouble with handset free activation.
Interestingly, for the second one, i just need to enable GCF after using the idone apps and it works perfectly. In fact, it has no issue with receiving phone call like the first one.
So, anybody understand what happen with my first phone after dial ##72786##, how can i get rid of handset free activation and unlock my phone like the second one. In fact, i have tried to flash the orginal room, factory reset, etc, but the handset free activation still appear and unable to receiving phone call after unlock as well.
oh, another information is my first phone has clean ESN and is not blacklisted

3g tablet call problem(need help)

Hello dear members,
I got a 8inch 3g 5.1 lolipop, Intel sofia geniu 900mhz mali450mp tablet,
But i have a problem,
When i insert a simcard to my tablet and when i was try a call to my tablet from another a number, tablet is not no reaction,
Same status; call number screen and agent screen no on the tablet menus, but this tablet is a 3g tablet.
İ think i need a custom room for this addition (for make a call and send a SMS)
İ was tried nova launcher but it was couldnt be useful

It's most likely sim locked. You will need to unlock it. A rom will not do it.
Not sure why you think a launcher would help. It has nothing to do with those functions.

sirrah thank you very much for your answer ,
i can connect to ethernet with my 3g service (vodafone H+)(registered imei)
but i cant accept to calls because no accept screen and no call ringtone but im hearing to call voice from other phone (dııııt..... dııııt.....)
example: A=my tablet , B=normal phone
B making a call to A
B's screen normal (im hearing call ring)
A's screen no reaction, just waiting on menu screen
please help :crying:

Then I'm betting it doesn't have the programs to accept phone calls. It is a known trick used by many China based devices. They advertise calling but cant get licensed to make calls so it leaves the apps out.

Uhmm, so cant we make anythink?

Unable to receive calls

Hello,
I bought a mi mix 2s some time ago and it's currently running the china rom because I can't unlock the bootloader the next 10 days.
First of all I can call other people and I can use mobile data. Also I'm able to receive calls if the sim is in my old oneplus one.
Now to my problem:
Today I realized that there must be a problem if someone calls me but I couldn't really figure out under what circumstances the issue appears.
However, I could figure out the following:
If I'm on wifi calls work most of the time
If I'm on 4g I don't receive calls most of the time
If I'm on H+ I receive calls most of the time
If the phone is locked I either get the call or the mailbox answers
If I don't get the call there are two things that happen on the phone that is calling me:
If it's a samsung theres just one loud beep and the call ends
If it's a LG there are fast beeps (similar like if the phone is busy)
Thanks in advance for any help

EDIT: Just figured out that the problem is that the phone takes too long to switch from 4g to 3g since VoLTE is not supported by my carrier... Found some guys in a forum who complained about the same problem but with a oneplus phone... I'm still open for any ideas that could fix that Maybe someone from germany here who uses O2/Eplus network and got the same problem?
EDIT2: http://en.miui.com/thread-935378-1-1.html Used this to enable VoLTE but can't test if it's working until tomorrow

Fixed it by the way by enabling VoLTE with the miui dialer code explained here
